Gordon, a former open-wheel driver now in NASCAR, contends that Patrick is at an advantage over the rest of the competitors because she only weighs 100 pounds. Because all the cars weigh the same, Patrick's is lighter on the race track.

'The lighter the car, the faster it goes,' Gordon said. 'Do the math. Put her in the car at her weight, then put me or Tony Stewart in the car at 200 pounds and our car is at least 100 pounds heavier.

'I won't race against her until the IRL does something to take that advantage away.'"
